EiPECIPICATION forming part of Letters Patent No. 355,246. dated December 28, 1886.

Application filed June 1, 1885. Renewed May 24, 1586. Serial No. 203,155, .(No model.)

To all whom it may concern:

Be it known that I, CHARLES AXEL BAOK- STROM, of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Centrifugal Liquid Separators, of which the following is a full, clear, and exact description.

This invention relates to the peculiar construction and arrangement of a centrifugal machine, whereby compound fluids may be separated more readily and more perfectly than has been accomplished heretofore.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of referenceindicate corresponding parts in the figures.

Figure 1 represents a vertical central section showing the several parts and their relations to the operation of separating fluids; Fig. 2, a plan or top View of glass globe and non-corrosive central receiver removed from the frame, and Fig. 3a central section showing a supplementary boX and coil of tubing.

A in the accompanying drawings represents a suitable frame, of metal, upon which are mounted the several operating parts composing the machine proper. The upper part of this frame A terminates in a saucer-shaped top, D, and the middle or stem thereof is formed into a sort of yoke, B, one side being cutaway to admit of fitting a driving-disk, E, to the spindle O 0'. To this frame A is fitted a sectional spindle, O G, the upper section, 0, terminating above the saucer-shaped top D, and

the lower section, 0, resting upon a loose frictional disk, 00, and the'whole supported upon a step, G. The two sections 0 O are held centrally in position by bushings F F, fitted to the frame A. The two sections 0 C forming the spindle meet in the hub O of the friction-disk E, centrally, the disk E being mounted upon and secured to the end of the lower section, 0, by a pin. The upper section, 0, simply rests upon the end of the lower section, and is driven by a pin, h, operating in aslot in the lower end thereof, as shown. By this construction and arrangement the upper section, 0, of the spindle is independent of and detachable from the lower driving-section, 0, when required.

To the upper end of the section 0 is attached a flattened glass, porcelain, or other suitable non-corrosive drum, H, with an opening, I, through its upper side. To this nonoorrosive drum H is fitted centrally therein a tubular receptacle, J, of porcelain covered 5 5 metal, or other noncorrosive material extending through the opening I and above the upper edge of the drum H, and terminating in a fiange, K, projecting outwardly and beyond the edge (6 of the opening I of the glass drum. From the lower side of this receptacle J extends a pipe, t, leading downward to the bottom of the drum H, so that the tluid passing through the receptacle J may be delivered into the drum H at its bottom.

The noncorrosive drum H and non-corrosive receptacle J are secured to the-upper end of section 0 of the spindle and held firmly in 1 position thereon between a cap, (I, on the end of the spindle and a washer, e, by means of two 72) nuts, b b, and to obtain a tightjoint between the drum H and central reservoir, J, which shall be somewhat yielding, and to preventinjury to the glass drum, rubber washers f are placed between the drum and iron washer, and 7 5 between the cap and bottom of the receiver, as shown.

To the rim or edge 9 of the saucer-shaped top D is fitted a removable cover, 1 divided into two or more compartments, m m, as may berequircd, and which is removed in order to introduce or remove the drum H, receiver J, and spindle G into or from the frame A, the drum and receiver being secured to the spindle.

I To the upper edge of the reservoir J are secured two disks, 1?, with openings n therein,- and at a distance apart to correspond with the spaces in m in the cover, the outer edges of these disks extending close to the inner edges of the inwardly-projecting flanges ofthe cover l, with only sufficient space between them to revolve freely without touching.

It will be understood that the disks 1? are united by a rim or edge forming a space or chamber between them, and in which rim or edge between the disks are formed the openings a, through which the lighter fluid is. to 'pass laterally into the annular channels at by the rotating motion of the drum, and thence discharged fron1 the machine through, the

lowermost spout, T, as shown.

To the sides of the cover I are arranged two fixed spouts, T T, leading from the annular spaces m m, to convey the separated fluid therefrom. To the receiver J is secured a pipe, 0, which enters and follows the inner periphery of the drum H to its center, its upper end terminating in the annular space on, Fig. 1, as shown, and through this pipe i the heavier fluid separated in the drum from the lighter fluid passes up and is delivered through the channel m over the disk P to the spout T. The two fluids being separated in the drum H, the heavier will be thrown 'to the periphery thereof to pass up and out through the tube 2', and the lighter fluid will rise and enter the annular space m through the openings u in the flange of the receiver, and so on out through the spout T.

Upon the shaft S, in a pillow-block, S, secured to the frame A,is mounted an adjustable disk, V, which is provided with a flexible or rubber rim, Z, upon its periphery, which bears against the lower surface of the disk E, by whichmotion isimparted (by friction) to the spindle to rotate the drum H and receiver J secured thereto, the power being applied to turn this disk V v bya belt-wheel, y. The disk V is adjustable back-and forth upon its shaft S, so as to vary the speed of the drum to compensate for the varying temperature of the fluid to be separated.

To the top of the cover I is fitted a detachable box, M, in which is a coil of tubing, M, through which coil the fluid to be separated passes,in order to vary the temperature thereof more or less as may be required before e11- tering the receiver J.

ter lubrication of the spindle, annular'grooves Z are made in the bushings, as shown in Fig. 1. The upper ends of these bushings are To facilitate the betformed into oil-cups W as a convenient method of supplying the bearings of the spindle with oil for a length of time.

It is quite evident that the number of compartments P may be increased, if required,

when the'fluid to be separated is composed of 5 tating drum with inlets and outlets for the fluids, and suitable mechanism for operating the drum, as such construction hasbeen used before by De Laval in 1881, butIintend to confine myself to the peculiar construction and arrangement described and shown in my-application.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a machine for separating compound fluids, in combination with the drum H, removable cover I, having inwardly-projecting flanges thereon forming the annular spaces m m, and disks 1?, with openings 01, the central receiver, J, secured to the bottom of the drum H, extending upward and through the upper side of the drum and terminating in a flange, K, outwardly beyond the edge of the drum, substant-ially as herein described.
